CVE-2023-32082

一、漏洞信息
 漏洞编号：[CVE-2023-32082](https://nvd.nist.gov/vuln/detail/CVE-2023-32082)
 漏洞归属组件：[etcd](https://gitee.com/src-openeuler/etcd)
 漏洞归属的版本：3.4.14,3.4.7
 CVSS V3.0分值：
  BaseScore：4.3 Medium
  Vector：CVSS：3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
 漏洞简述：
  etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.26 and 3.5.9, the LeaseTimeToLive API allows access to key names (not value) associated to a lease when `Keys` parameter is true, even a user doesn t have read permission to the keys. The impact is limited to a cluster which enables auth (RBAC). Versions 3.4.26 and 3.5.9 fix this issue. There are no known workarounds.

二、漏洞分析结构反馈
 影响性分析说明：
  在Etcd的版本3.4.26和3.5.9之前，存在一个安全漏洞，即使用户没有对键的读取权限，LeaseTimeToLive API 在Keys参数设置为true的情况下仍允许访问与租约关联的键名（而非键值）。这一问题可能影响启用了认证（RBAC）的集群。这意味着，在有权限控制的环境中，未经授权的用户可能通过此API获取到他们本不应访问的键名信息，从而导致信息泄露的风险。 上游修复方案: https://github.com/etcd-io/etcd/pull/15656/files
